Given that the volume of water remaining in the tank after t minutes is given by the function
where V is in gallons, 0 ≤ t ≤ 20 is in minutes, and t = 0 represents the instant the tank starts draining.
The rate at which water is draining four and a half minutes after it begins is given by
Therefore, the water is draining at a rate of 1,550 gallons per minute four ans a half minutes after it begins.

Answer:
It is not possible to take the square root of a negative number, but you can use imaginary numbers
square root of -16= 4i
well u can transfer the -5 in denominator to the right hand side
so x=1.2*(-5)
x=-6.0
Answer:
z = -17
Step-by-step explanation:
If the average of x and y is 11, then;
x+y/2 = 11
x+y = 2 + 11
x+y = 22 .... 1
similarly, if average of x, y and z is 5, then;
x+y+z/3 = 5
x+y+z = 3*5
x+y+z = 15
Since x+y = 22
22 + z = 5
z = 5 - 22
z = -17
Hence the value of z is -17
